HENRY FIELDS, OF BUHL, IDAHO.

ROTARY BUFFER.

Application filed May 31, 1924. Serial no. 717,124. 1

To all whom it may concern:

Be it known that I, HENRY FIELDS, a citizen of the United States, residing at Buhl, in the county of Twin Falls-and State of Idaho, have invented certain new and useful Improvements in a Rotary Buffer, of which the following is a specification.

This invention relates to new and useful improvements in rotary buffers for use principally upon shoe polishin machines.

One of the important objects of the present invention is to provide a device of the above mentioned character, wherein the rotary buffer may readily be detached from the driving means provided therefor.

A further object of the invention is to provide a device of the above mentioned character, wherein the buffer is of such a construction as to enable the felt material to be easily and quickly replaced when the same has become worn and further useless.

A still further o-fject of the invention is to provide a device of the above mentioned character, which is simple in construction, inexpensive, strong and durable and further more adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals designate like parts throughout the same:

Figure 1 is a sectional and elevational view showing the buffer, and I Figure 2 is an end elevation of the buffer.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the hub portion which is adapted to be supported on the drive shaft of the shoe shining machine, (not shown) and has one end thereof closed as illustrated at 2. An opening 3 is provided in the closed end of the hub portion 1 for engagement with means on the drive shaft whereby the hub portion may rotate with the drive shaft for the purposes of operating the rotary buffer associated therewith. Extending outwardly fro-m the closed end 2 of the hub portion 1 is threaded shank 4.

In Figure 1 of the drawing a buffer is shown wherein the same comprises the elong t d tubular member 8 which has-its inner end closed as illustrated at 9 and provided with a threaded opening" 10 for. receiving the threaded shank 4;. The tubular member is furthermore provided with the longitudinally extending circumferentially spaced slots 11 which extend from the outer end to a point adjacent the inner end and provide means for receiving and supporting the felt cleaning elements 12 in the manner clearly shown in Figure 2 of the drawing. The

radial slots are adapted to cooperate in pairs so that the intermediate portion of' each of the felt cleaning elements will be received in said cooperating pairs and be disposed within the tubular member 8 in the manner clearly illustrated in Figures 1 and 2 of the drawing.

For the purpose of preventing the accidental displacement of the felt cleaning members from the tubular member after the same have been inserted in the slots, I pro vide the cap 13 and the same is provided with an inwardly extending annular flange 141 for engagement with the annular-recess 15 provided in the tubular member 8, adjacent the outer end thereof in the manner clearly illustrated in Figure 1 of the drawing. It will of course be understood that the portions of the tubular member between the several slots will provide suflicient elasticity so as to enable the free ends thereof to be depressed in order to enable the cap to be removed or secured on the outer end of the tubular member.

The inner end of the hub portion 1 is provided with an outwardly extending annular flange 16 and the same provides a means for preventing the longitudinal movement of a bearing sleeve 17 which is disposed around the hub portion 1 between the tubular member and the flange 16 as clearly shown in Figure 1. This bearing sleeve, as is obvious, constitutes a hand grip which is adapted to be grasped by the operator .when using the device.

It will thus be seen from the foregoing description, that a rotary buffer has been provided wherein the elements comprising the same may be readily disassembled whenever necessary and is further of such a construction as to prevent the accidental disengagement of the cleaning member therefrom when the cap is locked on the outer end of the tubular member. A device of the above mentioned character, may be manufactured at a very low cost and the parts are further of such a construction as to render the same strong and durable.

WVhile I have shoWn the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be ,resorted'to as do not depart from the spirit of the invention and the scope of the appended claim.

Having thus described the invention, What I claim is A rotary buffer comprising a driven hub portion having one end thereof closed, a threaded shank extending outwardly from the closed end thereof, a tubular member having an open outer end and having longitudinally extending oircumferentially spaced slots provided therein extending from the outer end to a point adjacent the inner end thereof, cleaning elements supported in the radial slots, and means on the outer end of thetubular member for securing the cleaning elements against accidental displacement from said slots, said means comprising a cap provided With an inwardly extending annular flange, the outer end of said tubular member being provided With an annular recess to receive'said flange.

In testimony whereof I affix my signature.

HENRY FIELDS.
